Readapted from Curone et al. 2025. Left: ALMA disk continuum image of WRAY 15-1880 at 0.9 mm (331.6 GHz) from exoALMA survey (Curone et al. 2025). Right: residual plot generated by subtracting the frank model (sampled at the same uv-points of the observations) from the data and then imaged with CLEAN (Curone et al. 2025). The color scale represents the values of residual S/N in units of the observed noise (rms). In both panels the white circle represents the expected location of the candidate companion at the epoch of the ALMA observation, assuming a circular Keplerian motion on the disk plane.
